Eric-San,

Thanks for signing up!

I'll fix the coordinates in the FAQ -- thanks for the heads up.

For the places in the northwest that you mention, when you say 'These
are displayed as
Prohibited areas, instead of something like a "warning area"', I
assume you're referring to the airspace file and not to the chart? The
nfd2sua tool (the software behind the web page) does not translate
airspace items that are in the NFD as "Prohibited" -- they will go
into the output files as Prohibited (always forever and ever).

(See the caveats on the front page -- the NFD airspaces are tranposed
to the output files "as is"; if the NFD is wrong, your airspace file
will be wrong.)

The only translation done in the nfd2sua tool is Restrictive types for
OpenAir files. NFD restrictive types Alert, Caution, MOA, Training,
Warning and Danger areas are written as "AC Q" (for "danger").
(Restricted and Prohibited use R and P, as per the OpenAir description
at winpilot.com.)

Good suggestion on the lat/lon help -- will do.
